Breast cancer is the most common disease in women all over the world. In the structure of cancer morbidity, breast cancer ranks first and its frequency is steadily increasing. In the world, about 1.67 million new cases are diagnosed and every year more than 500,000 women die from breast cancer. Triple negative breast cancer (TNBC) is about 15–20 % of all breast tumors; is more common in women of fertile age. TNBC is characterized by a lack of expression of estrogen, progesterone receptors and HER-2/neu, which significantly complicates the treatment of this disease, which is characterized by aggressive course, the maximum risk of recurrence during the first 3 yearsafter surgical treatment, and rapid metastasis and decreased life expectancy. This article presents a review of the literature on the molecular-biological characteristics of TNBC. The article also describes the main approaches to targeted therapies for each subtype.
